This paper aims to examine the potential of waste biorefineries in developing countries as a solution to current waste disposal problems and as facilities to produce fuels, power, heat, and value-added products. The waste in developing countries represents a significant source of biomass, recycled materials, chemicals, energy, and revenue if wisely managed and used as a potential feedstock in various biorefinery technologies such as fermentation, anaerobic digestion (AD), pyrolysis, incineration, and gasification. However, the selection or integration of biorefinery technologies in any developing country should be based on its waste characterization. Waste biorefineries if developed in developing countries could provide energy generation, land savings, new businesses and consequent job creation, savings of landfills costs, GHG emissions reduction, and savings of natural resources of land, soil, and groundwater. The challenges in route to successful implementation of biorefinery concept in the developing countries are also presented using life cycle assessment (LCA) studies.
本文旨在探讨发展中国家的废物生物精炼厂作为解决当前废物处理问题的一种方案,以及作为生产燃料、电力、热能和增值产品的设施。如果明智地管理和利用废物作为各种生物精炼技术(如发酵、厌氧消化(AD)、热解、焚烧和气化)的潜在原料,发展中国家的废物代表着生物质、回收材料、化学品、能源和收入的重要来源。然而,在任何发展中国家选择或整合生物精炼技术都应基于其废物特性。如果在发展中国家开发废物生物精炼厂,可以提供能源生产、节省土地、创造新的商业和就业机会、节省垃圾填埋场成本、减少温室气体排放以及节约土地、土壤和地下水等自然资源。本文还使用生命周期评估(LCA)研究,介绍了在发展中国家成功实施生物精炼概念的挑战。
